We're dividing 507716 by 26 
We want to figure out the number of times 507716 can be divided by 26.

Step 1:
The number 26 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 26

On to step 2:
The number 26 fits into 50 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 26 away from 50, we end up with 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 26

Step 3:
When dividing 247 by 26, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 234 from 247 and we're left with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 26

Moving on to step 4:
137 divided by 26 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Subtract 130 from 137 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 26

Step 5:
The number 26 fits into 71 2 times, leaving a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 1952.0
The remainder is 19 after subtracting 52 from 71.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 26

On to step 6:
When dividing 196 by 26, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 19527.0
Deduct 182 from 196 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 26 fits into 140 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19527.5
Subtracting 130 from 140 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 19527.53
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
When dividing 220 by 26, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 19527.538
If we take 208 away from 220, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
If we divide 120 by 26, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 19527.5384
Deduct 104 from 120 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 26 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 19527.53846
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
The number 26 fits into 40 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 19527.538461
The remainder is 14 after subtracting 26 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
If we divide 140 by 26, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19527.5384615
Subtract 130 from 140 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
26 goes into 100 3 times with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 19527.53846153
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 19527.53846153, with a leftover of 2.2e-08.
